Having read all the discussion so far under TMG6 I held my data files in the shared directory C:\documents and settings\All Users\shared Documents\TMGDATA\ Dobree6 with the Exhibits as asub-directory to that. This directory was briefcased to a similar directory on my laptop. Both machines were running XP Home SP2. Both worked fine.
On upgrading to TMG7, I also had problems persuading the program to accept where I wanted to put the file. It does not accept a path to the shared directory on the grounds that it belongs to a different user (the install was on the basis that the program should be available to all users: the path wanted would put the files in a folder Dobree7). It then reported DobreeTMG_M.fpt was missing or invalid: when told to ignore that, it created a project file with only 15 (out of 464) sources. A renewed attempt with a fresh TMG6 backup provided a file with 30 sources.
On my (new) laptop with Vista and having accepted that I could not put the datafiles into a directory outside my own user area, I still found that it was losing my sources.
Any suggestions would be welcomed.
